| The database of fuze exploding-bolt is one main part of "The 10th 5-years National Defense Arming Pre-researching Project ?Analysis and Simulation of Fuze System and Fuze Virtual Prototyping Technology ".In this dissertation, based on the detailed analyze of the function and feasibility of the database system of fuze exploding-bolt, the collective scheme of the system is put forward. At the same time, the design of database accessing, the client interface design and the realizing technology of the system function modules ?data querying, data maintaining and data-reporter outputting etc. are studied.The characteristic of the fuze exploding-bolt parameters and the direction of the data stream are analyzed, and then the database of fuze exploding-bolt is programmed and built. The strategy of image documents stored/gotten and the technique of ActiveX Automation applied to the communication between the database system of fuze exploding-bolt and the 3D modeling software are described.After the analysis of the safeguard system and the user privilege management based on role about database, the feasible project to realize the login security and privilege management for the database system of fuze exploding-bolt are put forward, which improves the reliability of security of the entire system.The database system of fuze exploding-bolt we built has the features of practicability, expandability, flexible and effective data querying, all-purpose data-reporter, great information content and better security, it can be maintained easily and used expediently. The system can evidently shorten the time of the correlative exploding-bolt queried and improve the design efficiency. It can work as an independent knowledge base, opened in the mode of client application program, also can be embedded to the fuze virtual prototyping flatform as one part of the information resource of the fuze virtual prototyping. |
